DSIx6怎麼使能PSR

没人回复，自顶

PSR是一种低功耗形式，是怎么验证没任何反映的？

按说应该是液晶屏画会自刷新 保持住一个画面，不需接收外部video信号，可是我的主机关闭视频信号，液晶屏也跟着不显示了。所以我认为没有进入PSR模式，我对DSI86的操作有没错？ -- 向0xc8写 0x02

是能PSR条件如下：

1. Updates to the remote frame buffer located in sink must include two of the same static frame. The reason for
this requirement is the DSIX6 will never pass the first frame received on the DSI interface to the DisplayPort
interface. All subsequent frames will be passed to the DisplayPort interface.
2. If PWM signal is controlled directly by the DSIX6 and SUSPEND asserted, the REFCLK must remain active.
3. Changes in ambient light level must be relayed to the DSI96 along with updates to the remote frame buffer in
the sink.
4. Sink CRC verification must be disabled when the Assertive Display core is enabled. (applies only to the
SN65DSI96)

首先需要满足以上条件，然后再试试是能寄存器。
